As a non-reactive gas, nitrogen is used to support pipelines. Blackstone Pipeline & Environmental Solutions offers a full fleet of advanced equipment and an experienced team, to provide reliable, fit-for-purpose nitrogen solutions.
Displacement involves moving gases or liquids to make it safe to work in a particular section of a facility. Blackstone Pipeline’s experienced team and state-of-the-art nitrogen pumping equipment is designed to execute reliable displacement programs with predictable results.
Testing a facility’s mechanical integrity prior to use is fundamental to maintaining safe and effective operations. Blackstone Pipeline provides thorough and reliable pneumatic pressure testing services using data acquisition and analysis to provide accurate results that exceed the requirements for certification.
Helium leak testing helps find small leaks with inert, non-volatile compounds. If leaks are found in the system, the pressure is bled off, the connection is repaired, and the process is repeated until all leaks are eliminated. Additionally, this method of testing can help discover other issues, and can be used to simulate operational situations.
Nitrogen inerting is a technique that provides a safe working environment for carrying out hot work maintenance in the presence of hydrocarbons. Nitrogen inerting with Blackstone Pipeline is a fast, reliable, and cost-effective process that eliminates the risk of hydrocarbon explosions.
Purging involves moving or diluting gases or liquids until it becomes safe to work in that section of the facility or pipeline. The process is achieved using gas, often nitrogen, and requires detailed calculations and simulations. With our experienced team and state-of-the-art nitrogen pumping equipment, we design and execute reliable programs with predictable results.
Pipelines and operational facilities often require work to be done on active lines. Freeze plugs provide the ability to isolate a section requiring maintenance instead of purging the entire line.
Back pressure pads can play an important role in effective, efficient and safe pipeline operations. Using nitrogen, back pressure pads address two critical elements of flooding a pipeline with product: safety & product separation.
Hydrotests can play an essential role in establishing and maintaining effective pipelines. Our experienced project managers, operators and engineers can determine material strength, find gross leaks, and provide hydrotest solutions for pipelines, tanks, vessels, and facility piping.
When a valve cannot be isolated and work is required downstream, or when searching for leaks during a hydrotest, nitrogen assisted freezing and viscous fluid sealing can be effective solutions. Blackstone Pipeline’s nitrogen assisted freezing process uses closed-chamber freeze isolation to ensure safety, while temporarily quarantining the required section of pipe.
Drying is a critical step for maintaining the integrity and performance of your pipeline. Pipeline drying can be achieved using a variety of methods including nitrogen, air, methanol, and swabs.
There are many different reasons to leak test a pipeline and a variety of methods that can be used. Many leak testing methods rely on changing the system pressure, and/or injecting and detecting a chemical. Our expertise in pressure pumping and chemical processes enables us to perform expert leak detection services using a wide range of methods.
The most effective pipeline cleaning and pigging comes from a thorough investigation and understanding of line contents and deposits. Our system-specific programs use selective chemistries for black powder removal and abatement, wax removal, asphaltene removal, and engineered viscous fluid programs for inorganic deposit removal.
When a pipeline isn’t going to be used for an extended period of time, the possibility of corrosion can increase. Corrosion can affect the lifecycle of your pipeline, as well as its structural integrity. The introduction of corrosion inhibitors is an effective way to control this issue.

Leak detection is critical to maintaining pipeline integrity. Our flow proving technique involves simulating leaks at a variety of different flow rates. This procedure assesses the accuracy and reliability of your leak detection software to discover any issues and ensure safe and effective operations.

Our system-specific programs use selective chemistries for black powder removal and abatement, wax removal, asphaltene removal, and engineered viscous fluid programs for inorganic deposit removal. These proven chemical remediation techniques, combined with the best pigging technologies, ensure you get a comprehensively cleaned system.
Grouting, or filling a pipeline with cement, is an economical way to abandon the system. Using this in-place abandonment method requires a thorough analysis to ensure safety and structural integrity are maintained. Our experienced pipeline services team considers a wide range of factors to determine the best fill material, volume, and injection rates to be used, so you get a fit-for-purpose solution to get the job done right.
